Vector Table Address
Vector table area
The 36-byte area of addresses 0000H to 0023H is reserved as a vector table area. This area stores program
start addresses to be used when branching by RESET input or interrupt request generation. Of a 16-bit
program address, the lower 8 bits are stored in an even address, and the higher 8 bits are stored in an odd
address.
CALLT instruction table area
The subroutine entry address of a 1-byte call instruction (CALLT) can be stored in the 64-byte area of
addresses 0040H to 007FH.
